Megaboot (Auto(load)) version 2.6



Written by Martijn Groen 2001

Many thanks & credits to Edwin Blink for ideas and help and (a few) comments.

Megaboot was written for use with the new Atom HD-interface. System requirements: B-DOS 1.5a or higher and 256K memory. Processor: Z80B or higher recommended Handy: a DALLAS or SAMBUS-clock

Megaboot detects SAMDOS, MASTERDOS, B-DOS and MS-DOS disks. If a standard MS-DOS disk is detected 'MS-DOS disk' will be displayed (contents aren't displayed!). It is possible to rename a MS-DOS disk using B-DOS (the disk actually has two labels now!). Megaboot will display 'MS-DOS record' if such disk or record is detected (= MS-DOS disk + B-DOS id).

The usual stuff...

Edit key: abandon Megaboot

'F0' key: show last records

'F1' key: show next 16 records

'F4' key: show previous 16 records

'F7' key: show first records

'F2' key: selects Master drive

'F3' key: selects Slave drive

'F5' key: selects Floppy drive

'F6' key: load 'AUTO*' file (on root dir.) from CD-ROM.

SYMBOL O: open CD-ROM drive tray

SYMBOL C: close CD-ROM drive tray

Master or Slave is printed on the top-left of the screen.

'F8' key: run bootable disk. Handy if you want to boot another dos or load a protected game.

'F9' key: load autofile from current record. Autofile can be Basic or code.

Keys 1-7: select dir types and this number is printed after the Master or Slave message.

1: Autorun files: Basic & Code

2: Basic & Auto-Basic files

3: Autorun files & Screens

4: Autorun files & Code

5: Autorun files & Numeric arrays

6: Autorun files & String arrays

7: All (autorun) SAM dir types (Types 1,2,4,5,6 & 7)

In record mode:

Space or Return key: select record and display directory.

Cursor up or down: step through record list.

Cursor right: select record and display directory. Also, enter directory mode. The first file is highlighted, if it exists.

In directory mode:

Space or Return key: load file.

Cursor keys: step through directory.

Cursor left at left boundary: enter record mode.

Use the 'Mega Setup' program to add five or less of your favourite record(s) to the Megaboot program. When you press a key defined in the 'Mega Setup' program, the defined record will be selected and loads the Autofile from that record if it exists.
